Regions

Glacier.

Avalanche hazard will increase over the day as daytime warming and solar input weaken the upper snowpack. Pay attention to changing snow conditions on solar aspects if the snow becomes moist or wet.

Quality snow can be found on high polar aspects.

Confidence

Moderate

Avalanche Summary

No new avalanches were observed on Monday or Sunday.

On Saturday, a few small size 1.0 dry-loose avalanches were observed running from steep, rocky terrain features.

Snowpack Summary

Expect to find crusts on solar aspects in the morning and moist snow in the afternoon. Surface hoar is growing in shaded sheltered areas. Good snow quality is found on polar aspects above tree line.

The snowpack is generally strong and settled, however, the basal weakness of rounding facets/decomposing crust near the ground will remain a concern until the end of the season.

Weather Summary

Mainly sunny skies for Tuesday with light Northerly winds at ridgetop. Alpine temps will range from -12 to -5 with a freezing level up to 1650m.

5-15cm of snow is forecast for Friday night into Saturday.

Terrain and Travel Advice

  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
  • Use appropriate sluff management techniques.
  • Minimize your exposure time below cornices.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
